DIAGNOSIS FUNCTION

HOW TO READ DIAGNOSIS CODE

Connect M.U.T.-III to the 16-pin diagnosis connector, and read the diagnosis code. (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - Diagnosis Function

HOW TO ERASE DIAGNOSIS CODE

Connect M.U.T.-III to the 16-pin diagnosis connector, and erase the diagnosis code. (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - Diagnosis Function

note

However, the diagnosis code cannot be erased if it is a current trouble.

FREEZE FRAME DATA CHECK

By using M.U.T.-III, the freeze frame data can be checked. (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - Diagnosis Function

When detecting fault and storing the diagnosis code, the ECU connected to CAN bus line obtains the data before the determination of the diagnosis code and the data when the diagnosis code is determined, and then stores the ECU status of that time. By analysing each data using M.U.T.-III, troubleshooting can be carried out efficiently. The displayed items are as the table below.

DISPLAY ITEM LIST

Item No.	Item name	Data item	Unit
01	Odometer	Total driving distance when the diagnosis code is set	km
02	Ignition cycle	Number of times the electric motor switch is turned "ON" or "LOCK (OFF)" after the past failure transition	Number of counts is displayed.
03	Elapsed time after failure	Total elapsed time after a diagnosis code is generated	min^*
04	Current trouble accumulative time	Cumulative time for current malfunction of diagnosis code	min

note

^*: Overall elapsed time can be stored up to 65,534 minutes (45.5 days). The display of M.U.T.-III is fixed to 65,534 minutes after 65,534 minutes have elapsed. Or, if the battery is disconnected, the total elapsed time cannot be measured properly. Thus, 65,535 minutes (null value) is displayed. Since the value is calculated according to the information from the ETACS, a proper value may not be displayed when the ETACS time-out has occurred.
